System for watering live plants on a maneuverable rack

ABSTRACT

Examples provide a system for watering plants on a rack. A robotic device attaches to a portion of the rack and pulls or pushes the rack to a watering zone. A sprinkler device sprays water to evenly distribute water across all plants on the rack. The system determines quantity of water, duration of watering, and frequency of watering based on real-time sensor data and context data associated with the environment, historical watering data, condition of the plants on the rack and a set of customized maintenance rules based on the type of plants on the rack. When watering is complete, the robotic device returns the rack to a designated location and detaches from the rack. The robotic device then attaches to another rack having plants on it scheduled for watering. The watering schedule is updated dynamically based on changing weather and plant state.

BACKGROUND

In a garden center or other plant nursery, there are frequently dozensor even hundreds of different types of plants to be maintained. Eachtype of plant frequently requires varying amounts of sun exposure, soilmoisture levels, soil acidity (pH), watering frequency, fertilizerrequirements and/or soil composition for maintenance, health and growthof the plants. Managing these diverse maintenance requirements for everytype of plant on an individual basis is typically too time consuming,cost prohibitive and impractical in large-scale garden centers. In somesolutions, plants are watered simultaneously/uniformly by watersprinklers spread throughout the garden center. This automated wateringregime may lead to overwatering of some plants and underwatering ofothers, resulting in sub-optimal condition of plants and inefficientresource usage in plant maintenance.

SUMMARY

Some examples provide a system for watering plants on a maneuverablerack. The system includes plants associated with a maneuverable plantrack in a live plant center. The plant rack includes a set of wheelsconnected to an underside of a shelf member. An attachment point islocated on a portion of the shelf member. A robotic rack-driver devicemoves the plant rack to a watering zone of a frame-mounted sprinklerdevice. The robotic rack-driver device includes an attachment mechanismremovably connected to the attachment point on the plant rack. A motorprovides drive power to one or more wheels on the robotic rack-driverdevice. The robotic rack-driver device drives the plant rack along apre-determined route from an assigned location of the plant rack to thewatering zone. A control device on the robotic rack-driver deviceincludes a processor communicatively coupled to a memory. A controllercomponent is implemented on the processor. The controller componentanalyzes sensor data generated by one or more sensor devices andreal-time context data associated with the live plant center. Thecontroller component identifies a current state of at least one plant onthe plant rack based on a result of the analysis. A plant maintenancecomponent implemented on the processor generates a set of maintenanceinstructions for watering the plants on the plant rack. A set of one ormore sensor devices on the frame-mounted sprinkler device detects apresence of the plant rack within the watering zone. A sprinkler controlcomponent implemented on the frame-mounted sprinkler device triggersrelease of a quantity of water onto the plant rack via a set ofsprinklers for a predetermined watering duration specified in the set ofmaintenance instructions.

Other examples provide a computer-implemented method for dynamicallyscheduling watering of plants on a maneuverable plant rack. A set of oneor more sensor devices generates sensor data associated with at leastone plant on a selected plant rack in a live plant center. An analysiscomponent analyzes the sensor data and real-time context data associatedwith the live plant center using a set of status criteria. An updatedstatus of the at least one plant on the selected plant rack is generatedbased on the results of the analysis. A plant maintenance componentupdates a set of watering instructions for the selected plant rack basedon the updated status. The updated set of watering instructions includesa next scheduled watering time, a quantity of water and a duration ofwatering for the next scheduled watering time of the plant rack. Anavigation component on the robotic rack-driver device generates a setof navigation instructions. The robotic rack-driver device autonomouslydrives the selected plant rack from an assigned location to a wateringzone associated with a selected frame-mounted sprinkler device at thenext scheduled watering time based on the set of navigationinstructions. When a sensor device on the robotic rack-driver devicedetects release of water onto the selected plant rack within thewatering zone, the navigation component initiates a set of rotationalmotions maneuvering the selected plant rack within the watering zone toenable equal water distribution across the selected plant rack. Therobotic rack-driver device returns the selected plant rack to theassigned location of the plant rack when the sensor detects a cessationof water emissions from the rack-mounted sprinkler device.

Still other examples provide a robotic rack-driver device. An analysiscomponent implemented on at least one processor on the roboticrack-driver device analyzes sensor data associated with a live plantcenter and real-time context data associated with a plurality ofmaneuverable plant racks using a set of plant maintenance rules toidentify a selected plant rack for watering. An attachment mechanism onthe robotic rack-driver device couples to an attachment point on aportion of the selected plant rack. An electric motor provides drivepower to at least one wheel on the robotic rack-driver device. Therobotic rack-driver device moves the selected plant rack from anassigned location of the selected plant rack to a watering zoneassociated with a selected frame-mounted sprinkler device. A navigationcomponent generates instructions to move the selected plant rack througha set of rotational motions within the watering zone when theframe-mounted sprinkler device begins releasing water onto the selectedplant rack. The robotic rack-driver device returns the selected plantrack to the assigned location on condition a duration watering assignedto the selected plant rack is completed. The attachment mechanismreleases a locking mechanism to release the portion of the selectedplant rack from the robotic rack-driver device at the assigned location.

A more detailed understanding may be obtained from the followingdescription, presented by way of example, in conjunction with theaccompanying drawings. The entities, connections, arrangements, and thelike that are depicted in, and in connection with the various figures,are presented by way of example and not by way of limitation. As such,any and all statements or other indications as to what a particularfigure depicts, what a particular element or entity in a particularfigure is or has, and any and all similar statements, that may inisolation and out of context be read as absolute and therefore limiting,may only properly be read as being constructively preceded by a clausesuch as “In at least some examples, . . . ” For brevity and clarity ofpresentation, this implied leading clause is not repeated ad nauseum.

Referring to the figures, examples of the disclosure enable wateringplants on a maneuverable rack via a robotic rack-driver device and aframe-mounted sprinkler device. In some examples, the roboticrack-driver device autonomously identifies a rolling rack containing oneor more plants scheduled for watering. The robotic rack-driver deviceattaches/latches onto the rack and pulls or pushes the rack into a plantwatering zone associated with one or more sprinkler devices, such as,but not limited to, a frame-mounted sprinkler device. When the sprinklerdevice(s) finish watering the plants on the rack, the rack-driver deviceautomatically returns the rack of plants to a correct/assigned locationwithin a plant nursery/garden center. This enables more efficient plantwatering while improving quality of plant maintenance.

In other examples, the system uses sensor data regarding the conditionof plants on a rack to determine when the plants on the rack should bewatered, relocated to a warmer/protected area when there is a danger offrost, removing/culling damaged, wilted or out-of-season plants, etc.The system provides the robotic rack-driver device with instructions tomove a plant rack into the watering zone for watering and/or removed toa different location based on the condition of the plant(s) on the rack.This improves utilization of plant watering resources, improvesefficiency of plant maintenance and reduces water usage.

The memory 108 stores data, such as one or more applications. Theapplications, when executed by the processor 106, operate to performfunctionality on the computing device 102. The applications maycommunicate with counterpart applications or services such as webservices accessible via a network 112. For example, the applications mayrepresent downloaded client-side applications that correspond toserver-side services executing in a cloud.

In other examples, the user interface device 110 includes a graphicscard for displaying data to the user and receiving data from the user.The user interface device 110 may also include computer-executableinstructions (e.g., a driver) for operating the graphics card. Further,the user interface device 110 may include a display (e.g., a touchscreen display or natural user interface) and/or computer-executableinstructions (e.g., a driver) for operating the display.

The network 112 is implemented by one or more physical networkcomponents, such as, but without limitation, routers, switches, networkinterface cards (NICs), and other network devices. The network 112 maybe any type of network for enabling communications with remote computingdevices, such as, but not limited to, a local area network (LAN), asubnet, a wide area network (WAN), a wireless (Wi-Fi) network, or anyother type of network. In this example, the network 112 is a WAN, suchas the Internet. However, in other examples, the network 112 may be alocal or private LAN.

In some examples, the system 100 optionally includes a communicationsinterface component 114. The communications interface component 114includes a network interface card and/or computer-executableinstructions (e.g., a driver) for operating the network interface card.Communication between the computing device 102 and other devices mayoccur using any protocol or mechanism over any wired or wirelessconnection. In some examples, the communications interface component 114is operable with short range communication technologies such as by usingnear-field communication (NFC) tags.

In at least some examples, the communications interface component 114enables communications between the computing device 102 and otherdevices, such as but not limited to a set of one or more roboticrack-driver devices 116 for moving racks of plants around a plantcenter, a set of one or more sprinkler devices 118 for spraying wateronto plant racks and/or a plurality of data sources 120 providingreal-time context data 122 associated with the plant center.

The plurality of data sources provides the real-time context data 122associated with one or more plants in the live plant center, one or moreplant racks within the live plant center, one or more areas of the liveplant center, the conditions within the live plant center and/or theconditions/weather surrounding the live plant center. The plurality ofdata sources 120 in some examples includes, without limitation, one ormore news feeds, one or more weather feeds and/or access to one or moreshipping and receiving databases/records. A shipping and receivingdatabase/record includes data associated with expected dates and/ortimes of arrival of a delivery or shipment of plants, inventory ofplants to be delivered on a specific date, delays associated with anexpected delivery/shipment of plants or any other data associated withorders of plants to be delivered or shipped to the live plant center.

The system 100 may optionally include a data storage device 124 forstoring data, such as, but not limited to a set of per-plant maintenancerules 126. The set of per-plant maintenance rules 126 includes one ormore rules for maintaining a specific plant or a type of plant. Forexample, the per-plant maintenance rules 126 may include a rulespecifying that succulent plants are to be watered one time per weekuntil the soil in each pot/container is thoroughly soaked and waterbegins to run out through the drain holes.

The data storage device 124 may include one or more different types ofdata storage devices, such as, for example, one or more rotating disksdrives, one or more solid state drives (SSDs), and/or any other type ofdata storage device. The data storage device 124 in some non-limitingexamples includes a redundant array of independent disks (RAID) array.In other examples, the data storage device 124 includes a database.

The data storage device 124 in this example is included within thecomputing device 102 or associated with the computing device 102. Inother examples, the data storage device 124 may be a remote data storageaccessed by the computing device via the network 112, such as a remotedata storage device, a data storage in a remote data center, or a cloudstorage.

The memory 108 in some examples stores one or more computer-executablecomponents. Exemplary components include a plant maintenance component128 that is executed by the processor 106 of the computing device 102.The plant maintenance component 128 generates a set of maintenanceinstructions 130 for watering one or more plants on a selected plantrack.

A plant rack is a rolling device for displaying and/or transportingplants. A plant rack may include one or more shelves. In other examples,a plant rack may be a rolling dolly or rolling platform for transportingtrays of small plants or large/tall plants.

The set of maintenance instructions includes a per-rack wateringschedule 132. The per-rack watering schedule 132 includes instructionsfor watering plant(s) on a selected plant rack. The wateringinstructions may include a next scheduled watering time, a quantity ofwater and/or a duration of watering for the next scheduled watering timeof the plant rack.

In other examples, the plant maintenance component 128 performs one ormore update(s) 134 of a pre-existing set of maintenance instructions.The update(s) 134 are performed in response to changes in context dataand/or changes in sensor data indicating an increase or decrease inwatering of plant(s) on a one or more plant racks. For example, a changein sensor data and/or context data may indicate changes instatus/condition of one or more plants on a rack, a change inweather/temperature, a change in delivery/shipping schedule, etc.

In this non-limiting example, the plant maintenance component isexecuted on the computing device 102. In other example, the plantmaintenance component 128 may be implemented on one or more of therobotic rack-driver devices and/or the rack-sprinkler devices. In otherwords, the analytics performed by the plant maintenance component may beperformed entirely on a robotic rack-driver device or the analytics maybe performed by two or more robotic rack-driver devices sharing theprocessor load. In these example, a load balancer may be utilized todivide the processing load among the robotic rack-driver devices and/orone or more rack-sprinkler devices.

FIG. 2 is an exemplary block diagram illustrating a live plant center200 including at least one robotic rack-driver device and at least onesprinkler device. The live plant center 200 is a plant nursery, a gardencenter or other retail location storing a plurality of plants 202 on aset of one or more plant racks, such as, but not limited to, the plantrack 204. The plant rack 204 is maneuverable. The plant rack includesone or more rollers (wheels) enabling the plant rack to be pulled,pushed or otherwise moved by a robotic rack-driver device 206.

The robotic rack-driver device 206 is an autonomous robotic deviceincluding an attachment mechanism 208 that latches onto an attachmentpoint 210 on the plant rack 204. The attachment point is a device orportion of a device configured to complement/conform with the attachmentmechanism on the robotic rack-driver device.

When the attachment mechanism 208 engages the attachment point 210, theattachment mechanism activates a lock 212 to prevent the plant rack 204from detaching from the robotic rack-driver device 206 before therobotic rack-driver device 206 releases it.

The robotic rack-driver device 206 selects a specific plant rack basedon a rack identifier (ID) 214 on each plant rack. The rack ID 214 is anidentifier distinguishing the plant rack 204 from other plant racks. Therack ID 214 may be implemented as a universal product code (UPC), amatrix barcode, a quick response (QR) code, a radio frequency identifier(RFID) tag, a label, or any other type of barcode or identifier. Therobotic rack-driver device 206 in this example scans the rack ID 214using one or more sensor device(s) 216. The sensor device(s) 216 mayinclude, without limitation, a barcode reader, a camera for capturing animage of the rack ID 214, an RFID tag reader, a QR code reader, or anyother type of device for reading the rack ID 214.

The robotic rack-driver device 206 may optionally include a device ID218 identifying the robotic rack-driver device 206. A user or othersmart device scans/reads the device ID 218 to identify a selectedrobotic rack-driver device if there are two or more robotic rack-driverdevices in the live plant center 200.

The plant rack 204 includes a set of one or more water absorbent mats220 in some examples. The plurality of plants 202 on the plant rack 204are arranged on one or more shelves. Each shelf in this non-limitingexample includes a water absorbent mat laying on a surface of the shelf.One or more plants are placed on top the mat on a shelf. When the plantson the rack are watered, the water is sprayed onto the water absorbentmat. The mat holds the water, which is absorbed through one or moreholes in the plant pot/container. In this manner, the plants are wateredvia the set of water absorbent mats rather than spraying the wateracross the top of the plants or pouring the water into the pot/containerfor each plant.

The robotic rack-driver device 206 may optionally be powered orrecharged via a poser supply 222. The power supply may be implemented asa set of batteries, an electrical power source, one or more solar panelsattached to the robotic rack-driver device 206, or any other powersource.

The robotic rack-driver device 206 in this example generates sensor datavia one or more sensor devices on the robotic rack-driver device 206. Inother examples, the robotic rack-driver device 206 may receive sensordata 224 from a set of one or more sensor devices 226 within the liveplant center 200. The sensors in the set of sensor devices 226 may belocated on plant displays, plant racks, walls, ceilings, onpoint-of-sale (POS) devices or located anywhere else within the liveplant center. A plant display may include a hanging plant display, atable or other fixture on which plants are resting, a bin, a shelf, acabinet, a counter, or any other display.

In this example, the robotic rack-driver device 206 includes a controldevice 228 including a memory 232 communicatively coupled to a processor230. The processor optionally executes a plant maintenance component forgenerating maintenance instructions, such as, but not limited to, theplant maintenance component 128 in FIG. 1 . The instructions mayidentify a plant rack for watering, identify a date and/or time forwatering plants on the plant rack and/or instructions to move the plantrack to a different location. For example, if sensor data or contextdata indicates a temperature decrease (possibility of frost), theinstructions may indicate the robotic rack-driver device 206 should movethe plant rack 204 inside a protected/sheltered/heated area or be placedbelow a plastic cover/roof or other protection from the weather.

In other examples, the robotic rack-driver device 206 receives theinstructions 236 from a remote computing device, such as a user device234. The user device is a computing device for generating a set ofmaintenance instructions 130, such as, but not limited to, the computingdevice 102 in FIG. 1 . A user may utilize the user device to manuallytrigger watering of a cart/initiate watering by the sprinkler device ifthe sprinkler fails to begin watering automatically. In other examples,the user device may be utilized by the user to manually trigger arobotic rack-driver device to attach to a selected plant rack forwatering. In other words, a user may manually enter a rack ID and promptthe robotic rack-driver device to move the selected rack to the wateringzone for watering at a time when watering is not scheduled (unscheduleddate/time) or otherwise outside of the scheduled watering schedule forthe selected rack or in addition to scheduled watering times.

The robotic rack-driver device 206 moves the plant rack 204 from anassigned location where the plant rack 204 is currently located to awatering zone associated with a frame-mounted sprinkler device 238 atthe next scheduled watering time provided in the instructions 236. Therobotic rack-driver device 206 may utilize a set of navigationinstructions to guide the robotic rack-driver device 206 from theassigned location to the location of the frame-mounted sprinkler device238.

The frame-mounted sprinkler device 238 includes one or more sprinklerheads mounted to a frame. The frame may be an A-frame, arch shaped,rectangular shaped, or any other shape. In this example, theframe-mounted sprinkler device 238 includes a set of water pipes orwater lines within a set of hollow pipes forming the frame. The set ofwater pipes/lines carry water from a water supply 240 to the sprinklerhead(s) for release onto the plant rack 204.

The frame-mounted sprinkler device 238 optionally includes a set of oneor more sensor devices 242. A sensor device in the set of sensor devices242 may include a barcode reader, image capture device (camera), motionsensor, pressure sensor, weight sensor, heat sensor, temperature sensor,hygrometer, proximity sensor, light sensor, or any other type of sensordevice.

The frame-mounted sprinkler device 238 in this example transmits thesensor data generated by the set of sensor devices 242 to the userdevice 234 and/or the robotic rack-driver device 206. In other examples,the frame-mounted sprinkler device 238 optionally analyze sensor datagenerated by the set of sensor devices 242 to detect the presence of theplant rack 204 within the watering zone of the frame-mounted sprinklerdevice 238. When the frame-mounted sprinkler device 238 detects theplant rack 204 in the watering zone, the frame-mounted sprinkler device238 automatically begins spraying water onto the plant(s) on the plantrack, the set of water absorbent mats and/or the pots/containers holdingthe plants. In other examples, the frame-mounted sprinkler device 238does not begin spraying water until the frame-mounted sprinkler device238 receives a signal/instruction from another device, such as, but notlimited to, the robotic rack-driver device 206, the plant rack 204 orthe user device 234.

The watering zone is an area associated with the frame-mounted sprinklerdevice 238 which receives water from the frame-mounted sprinkler device238. In other words, items within the watering zone are within range ofthe sprinkler(s) on the frame-mounted sprinkler device 238. Itemsoutside the watering zone do not receive any water (out of range) of theframe-mounted sprinkler device 238.

The live plant center 200 in at least some examples includes a set ofdrains 244 for collecting/reclaiming water run-off from the plant rack204 during watering. The set of drains may be located in the floor or ina bottom portion of the sprinkler device or any other device forcapturing water run-off from the plant racks.

The reclaimed water 248 is collected in a water receptacle. The waterreceptacle 246 may include one or more water storage containers orreservoirs for holding water. The water receptacle may include one ormore sensor devices for measuring/determining quality of the reclaimedwater, identify any impurities or additives in the water, temperature ofthe water, etc. For example, if fertilizer is added to the water, thesensor device detects the concentration of the fertilizer in parts permillion (PPM). The sensor may also be utilized to identify hard water,water which is too hot or too cold for use on the plants, etc.

The reclaimed water 248 acts as an additional water supply for theframe-mounted sprinkler device 238. The frame-mounted sprinkler device238 re-uses the reclaimed water to water plants on the plant rack 204and/or other plant racks.

In at least some examples, the water may be filtered through a set offilters 250 to remove particulate matter 252 or otherimpurities/additives from the reclaimed water 248 prior to storage orprior to use. In other examples, the frame-mounted sprinkler device 238may include one or more filters to filter the reclaimed water 248 priorto spraying the reclaimed water on other plants. In these examples, theset of sensor devices 242 may also include water quality sensors fordetecting impurities, additives, particulate matter and other contentsof the water supply 240 prior to spraying on the plant rack(s). If thesensor data indicates the water is too acidic or otherwise containsundesirable additives, an instruction may be generated instructing auser to add a neutralizer to the water supply 240 to counteract theeffects of the undesired elements.

The water reclamation system in this example reclaims water run-off fromthe plant racks during watering. In other examples, the waterreclamation system catches rain water and/or utilizes rainwater capturedin rain barrels or other water receptacles.

In still other examples, the system may output instructions to the userdevice instructing a user to manually remove one or more plants from aselected plant rack. For example, if the system determines that one ormore plants on a given rack are yellowing, dying, or otherwise should beremoved from the rack, the system may output a notice to a user deviceinstructing a user to remove those plants. The notice may include aplant ID identifying the plants to be relocated to a clearance area,donation area or other disposal area.

In yet other examples, the system outputs instructions to a drone orother autonomous robot instructing the drone to remove one or moreplants from a given plant rack if the system identifies those plantshave having poor quality, out-of-season, ready for markdown/clearance,or otherwise designated for removal from the cart.

The system may also output a notification to a user device or otherautonomous robot/drone to remove one or more plants which have beenincorrectly placed onto a selected plant rack. For example, if a plantrack contains all bushes, and a user mistakenly misplaces an annualflowering plant on the plant rack, that succulent plant would besubjected to non-optimal watering schedules suited to bushes rather thanannual flowers. The notice may include a rack ID identifying the plantrack and a plant ID identifying the annual plant to be removed from theplant rack and returned to its correct location elsewhere in the plantcenter.

The system may also output notifications to a user device and/or otherautonomous robot/drone to relocate/reposition items on a cart to improveoverall appearance/display value of the item. For example, if plants arearranged so that all red flowering plants are grouped together, andwhite flowering plants are grouped together on another rack, the systemoutputs a notification requesting removal/relocation of any whiteflowering plants mistakenly mixed in with the red flowering plants toimprove appearance of the plants and display value of the displays, aswell as ease of locating desired items.

FIG. 3 is an exemplary block diagram illustrating a robotic rack-driverdevice 300. The robotic rack-driver device 300 includes a set of one ormore wheels 302 having a set of one or more brakes 304. When a brake isapplied to one of the wheels, a regenerative braking system 306 convertskinetic energy into power to recharge one or more batteries in a set ofbatteries 308. The set of batteries 308 may be utilized to power a motor310. The motor may be implemented as an electric motor or any other typeof motor generating drive power 312 to turn one or more of the wheels.

In at least some example, a memory 314 includes an analysis component316 implemented by at least one processor on the robotic rack-driverdevice 300. The analysis component analyzes sensor data 320 generated bya set of sensor devices 322 associated with at least a portion of a liveplant center with real-time context data associated with a plurality ofmaneuverable plant racks using a set of plant maintenance rules. Theanalysis component 316 generates a status 318 of one or more plants onone or more plant racks based on a result of the analysis. A plantmaintenance component identifies 324 utilizes the status 318 to identifya selected plant rack for watering next.

A navigation component 326 generates a set of navigation instructions328 for moving the selected plant rack to a watering zone and/or movethe selected plant rack through a set of rotational motions within thewatering zone during watering. The navigation component 326 optionallyalso generates instructions to return the selected plant rack to theassigned location of the selected plant rack when watering of plants onthe plant rack is completed. For example, if the plant rack ispositioned near an entry way, when watering is complete, the roboticrack-driver device returns the plant rack to the same location near theentry way.

In other example, the robotic rack-driver device 300 may move the plantrack to a different location after watering. For example, if the plantson the plant rack will soon be out-of-season or the sensor dataindicates the plants on the plant rack are slightly yellowing/wilted,the plant rack is moved to a clearance area.

A controller component 330 on the robotic rack-driver device 300 inother examples triggers activation of an attachment mechanism 332 toattach to an attachment point on a selected plant rack. When attachmentis complete, the controller component 330 activates a locking mechanism334 to secure the plant rack to the robotic rack-driver device.

The analysis component includes an artificial intelligence (AI)with machine learning (ML) permitting the system to analyze real-timedata using historical data and training data using pattern analysis toimprove watering schedules and plant maintenance/plant quality.

The analysis component performs analytics in this example remotely fromthe robotic rack-driver device to reduce resource usage on the roboticrack-driver device. The cloud server maintains network connectivity withdevices such as the robotic rack-driver device, sprinkler device and/orplant racks via the network.

In this example, the analysis component 1402 generates a status update1404 for a plant based on results of analysis of sensor data and contextdata.

FIG. 16 is an exemplary flow chart illustrating operation of thecomputing device to water plants on a plant rack via a frame-mountedsprinkler device. The process shown in FIG. 16 may be performed by acomputing device, such as the robotic rack-driver device in FIG. 1 .

The process begins by analyzing sensor data and context data usingstatus criteria at 1602. The robotic rack-driver device generates astatus update for one or more plants on a plant rack at 1604. Therobotic rack-driver device determines if a change in a watering scheduleis needed at 1606. If yes, the robotic rack-driver device updateswatering instructions for the plant rack at 1608. The roboticrack-driver device determines if it is time to water plants on the plantrack 1610. If no, the robotic rack-driver device waits 1612 until it istime to water the plants on the plant rack.

The robotic rack-driver device moves the plant rack to the water zone at1614. The robotic rack-driver device determines if watering is completeat 1616. If no, the robotic rack-driver device waits until watering iscompleted. The robotic rack-driver device returns the plant rack to theplant rack's original location at 1620.

Additional Examples

In some examples, the system utilizes real-time weather data and othersensor data to forecast/predict watering requirements for plant and/ormodify watering schedules for plants in a garden center. A roboticdevice moves plants on a rack through a watering frame when needed basedon the real-time data. The system utilizes sensor devices to determinewhen a rack containing one or more plants is within a watering zone ofthe sprinkler device. The system also analyzes the sensor data (imagedata, scanner data, barcode data) to identify the type of plants on eachrack.

In some examples, each type of plant or plant category has a differentwatering schedule and/or different additives added when watering. In oneexample, plants are placed into eight different plant type categories.Plants in each of the eight categories receives different amounts ofwater during watering. The plants in each category may also be wateredwith different frequency. For example, cacti may be watered lessfrequently than annuals. Likewise, plants in the category for annualflowers may be watered more frequently each day or each week than plantsin the category for bushes. In other words, racks containing annuals arerun through the sprinkler device more frequently than racks containingbushes or cacti.

In other examples, the system maintains a blockchain ledger associatedwith each rack/type of plant as a step in the chain of custody. In theseexamples, the system records date, time and frequency of watering,weather, and duration of watering/quantity of water placed on eachplant. The blockchain record is maintained from day of delivery of theplant to the plant center all the way through final markdown and/orsale. The blockchain enables the system and/or a user to understand thepath of the rack through the supply chain. In other words, thehistorical data/blockchain data identifies which grower/supplierprovided the plant, how the plant was handled/maintained through thesupply chain and store, when watering occurred, when fertilizationoccurred, type of fertilizer applied, quantity of water and/orfertilizer applied, any other additives/neutralizers applied,temperature exposures by the plant, etc. This data enables improvedquality control and better maintenance of plants.

The system provides real-time updated watering of plants based onprevious watering of the plants, current weather (temperature andhumidity), water requirements for each type of plant, and/or other localenvironment conditions associated with the plant center where the plantsare located.

The robotic rack-driver device in some examples downloads wateringinstructions and/or navigational directions from a cloud on a regularbasis, such as, but not limited to, four to six times per day. Theprocessing/analysis of real-tie data in this example occurs in the cloudserver rather than on the robotic rack-driver device. The instructionsidentify which rack a robotic rack-driver device should attach to andtake to the watering zone for watering. The robotic rack-driver devicecommunicates via the network with the sprinkler device to initiatewatering when the robotic rack-driver device arrives in the wateringzone with the rack.

The robotic rack-driver device in other examples collects sensor datathroughout the day. The sensor data may be stored on the roboticrack-driver device or uploaded to the cloud or other storage device. Theuploaded data may include when plants on each rack are watered, how muchthey are watered (quantity), frequency of watering, temperature,humidity, heat off concrete, wind, frost, water quality, etc.

The barcode or other plant ID on a given plant may include historicalinformation for the plant, such as, but not limited to, growerinformation, shipment dates, supplier, dates of arrival at the plantcenter, frequency of watering, time of day, etc. The robotic rack-driverdevice has real-time access to plant data (item data) on the storesystem, cloud server or other data storage.

The system determines the state of plants on each rack—if plants shouldbe moved to clearance, moved to a location with more light/sun, increasewatering frequency, etc. Machine vision analytics are utilized todetermine the plant's condition—browning/yellowing foliage, presence ofperforations, poor pot drainage, or other undesirable conditions. Thesystem documents/records data associated with quality, infestations,wilting, yellowing, loss of foliage, bloom, dead heads, etc.

In an exemplary embodiment, one or more of the exemplary embodimentsinclude one or more localized Internet of Things (IoT) devices andcontrollers. As a result, in an exemplary embodiment, the localized IoTdevices and controllers can perform most, if not all, of thecomputational load and associated monitoring and then later asynchronousuploading of summary data can be performed by a designated one of theIoT devices to a remote server. In this manner, the computational effortof the overall system may be reduced significantly.

In addition, in an exemplary embodiment, the periodicasynchronous uploading of summary data may include a key kernel indexsummary of the data as created under nominal conditions. In an exemplaryembodiment, the kernel encodes relatively recently acquired intermittentdata (“KRI”). As a result, in an exemplary embodiment, KRI includes acontinuously utilized near term source of data, but KRI may be discardeddepending upon the degree to which such KRI has any value based on localprocessing and evaluation of such KRI. In an exemplary embodiment, KRImay not even be utilized in any form if it is determined that KRI istransient and may be considered as signal noise. Furthermore, in anexemplary embodiment, the kernel rejects generic data to provide amodified kernel (“KRG”) by filtering incoming raw data using astochastic filter that thereby provides a predictive model of one ormore future states of the system and can thereby filter out data that isnot consistent with the modeled future states which may, for example,reflect generic background data. In an exemplary embodiment, KRGincrementally sequences all future undefined cached kernels of data tofilter out data that may reflect generic background data. In anexemplary embodiment, KRG further incrementally sequences all futureundefined cached kernels having encoded asynchronous data to filter outdata that may reflect generic background data.
